Equilibrium

Question 1

what happens at equilibrium - remember closed system

Answer 1

The concentrations of the reactants and products remain constant and the rates are equal.

Question 2

What do you have to do to the concentration to shift the equilibrium to the right

Answer 2

Increase the concentration of reactants or decrease the concentration of products

Question 3

What do you have to do to the concentration to shift the equilibrium to the left?

Answer 3

Increase the concentration of products or decrease the concentration of reactants

Question 4

What does increasing the temperature do?

Answer 4

Favours the endothermic reactions (+ve)

Question 5

What does decreasing the temperature do?

Answer 5

Favours exothermic reactions (-ve)

Question 6

What does increasing pressure do? (remember only gases are affected)

Answer 6

Increasing pressure favours side with the least moles of gaseous molecules

Question 7

What does decreasing the pressure do? (remember only gases are affected)

Answer 7

Decreasing pressure favours the most moles of gaseous molecules

Question 8

What do catalysts do to equilibrium?

Answer 8

Catalysts have no impact on the position of equilibrium however both forward and reverse reactions are sped up
